Abstract：Objective Intelligent detection algorithm based on Magphan SMR 170 was designed to measure the space linearity automatically
in this paper. Methods The randomized Hough transform (RHT) circle detection algorithm was applied to extract the target with the shape
feature, and the improved algorithm was proposed to accelerate the detection speed. Results Hough detection algorithm realized the
extraction of target, and satisfactory results had been obtained on both the detection accuracy and speed (P=0.10009>0.05). Conclusion
Intelligent detection algorithm could replace traditional method of artificial detection for space linearity.
